Question

read the source of the allusion.
in greek mythology, the prince cadmus kills a dragon. he then plants the dragon’s teeth in the ground. the dragon’s teeth become soldiers, who fight one another.
what is the meaning of the allusion in the sentence below?
by eating the last cookie, derek planted the dragon’s teeth of his quarrel with ashley.
options: the result of an important talk or meeting; the cause of a fight or struggle

Explanation:

In the Greek myth, dragon's teeth planted become fighting soldiers. In Derek's case, the cookie (like dragon's teeth) is the cause of his quarrel with Ashley. The option "the cause of a fight or struggle" matches, as the dragon's teeth (here, the cookie) start the fight/quarrel. The other option is about a result of a talk, which doesn't fit.

Answer:

the cause of a fight or struggle
